Thomson Model of an atom
The description of Thomson’s atomic model is one of the many scientific models of the atom. It was proposed by J.J Thomson in the year 1904 just after the discovery of electrons. However, at that time the atomic nucleus was yet to be discovered. So, he proposed a model on the basis of known properties available at that time. The known properties are:
Atoms are neutrally charged
Negatively charged particles called electrons are present in an atom.
According to J.J Thomson's model of atom he described that a spherical like structure is an atom and he compare the structure with watermelon in which electron are embedded like seeds in watermelon and protons are present the free space of atom . Hence the atom was unstable
